A large-scale study led by the University of Exeter analyzed 415,980 electronic medical records of older adults in England. People aged 75 or over with low blood pressure (below 130/80) had increased mortality rates in the follow-up, compared to those with normal blood pressure. This was especially pronounced in 'frail' individuals, who had 62% increased risk of death during the 10-year follow-up.
The brain seems to have two different systems through which we can put ourselves into the shoes of someone else. These two systems mature at different times such that only 4-year-olds can understand what another person is thinking, and not, as some have assumed, 1-year-olds. These are the findings from a new study in the journal PNAS.
A novel structure of a so-called 'neurotransmitter: sodium symporter' has been mapped at the University of Copenhagen. The discovery adds to the researchers' knowledge of neurotransmitters in the brain and may lead to better drugs for, for example, ADHD, depression and epilepsy.
When 119 young adults consumed a meal while playing a simple computer game for 15 minutes, they ate significantly less than when they ate the same meal without distractions, said lead author Carli A. Liguori, an alumna of the University of Illinois at Urbana-Champaign's food science and human nutrition program.
University of Texas System researchers have pinpointed a molecule that the tuberculosis bacterium manufactures to induce the coughing that spreads the disease by triggering a pain-receptor response.

Researchers at the Department of Energy's Oak Ridge National Laboratory have used Summit, the world's most powerful and smartest supercomputer, to identify 77 small-molecule drug compounds that might warrant further study in the fight against the SARS-CoV-2 coronavirus, which is responsible for the COVID-19 disease outbreak.
Diseases often pile on, coinfecting people, animals and other organisms that are already fighting an infection. In one of the first studies of its kind, bioscientists from Rice University and the University of Michigan have shown that interactions between pathogens in individual hosts can predict the severity of multipathogen epidemics.
The news this week was a study in uncertainty. U.S. President Donald J. Trump made sweeping, confident, and sometimes baffling pronouncements. Global stock markets plunged, climbed, then plunged again. And researchers continued to analyze — and learn from — the ever-larger trove of data about the virus.
Since December, the novel coronavirus spreading across the globe has infected more than 98,000 people. As fear of a pandemic grows among the public, online marketers are taking note, churning out a steady stream of guidebooks and other publications that claim to hold the secret to surviving the outbreak.

The gut microbiome, which is a collection of numerous beneficial bacteria species, is key to our overall well-being and good health. Recent studies have linked the gut microbiome with several beneficial properties, such as aiding in the development of our immune system and warding off pathogen infections.
In a study of epilepsy patients, researchers monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns of the cells that occurred when patients learned a word pair were replayed fractions of a second before they successfully remembered the pair.
An international team of scientists has launched a comprehensive overview of all proteins expressed in the brain. The open-access database offers medical researchers an unprecedented resource to deepen their understanding of neurobiology and develop new, more effective therapies and diagnostics targeting psychiatric and neurological diseases.
Pioneering research has devised the first system that classifies lakes globally, placing each of them in one of nine 'thermal regions.' This will enable scientists to better predict future warming of the world's lakes due to climate change, and the potential threat to cold-water species such as salmon and trout.
Nasa's Veggie system will enable astronauts to safely grow nutritious fresh food Experiencing weightlessness, gazing back at the Earth as a pale blue dot and the adrenaline rush of being propelled into orbit at 20,000mph: life as an astronaut has various unique attractions. The food is not among them, with space travellers over the years enduring delicacies such as freeze-dried ice-cream, liquid
Alzheimers sjukdom är en komplex och svårdiagnostiserad sjukdom eftersom symtomen överlappar med andra liknande sjukdomar. Men nu har forskare funnit en markör i blodet som mer exakt kan diagnostisera Alzheimer i de tidiga stadierna av sjukdomen.
Som Sveriges första klimathandläggare 1988 vet Mats Engström vad han pratar om när han skildrar miljöarbete inifrån. Han har även varit biträdande statssekreterare på Miljödepartementet och politiskt sakkunnig åt dåvarande Anna Lindh på UD. Med de stora problem vi står inför nu behöver vi blicka bakåt i miljöhistorien och analysera framgångsfaktorerna och lära av dem, menar Mats Engström.
Bokens ambition beskrivs i den långa undertiteln: Det dolda mönstret i allt – om vad som förenar möss, människor, megastäder och multinationella företag. Författaren Geoffrey West är en fysiker som blev intresserad av biologins villkor och sadlade om till komplexitetsforskare. Skalning handlar om hur olika mätbara storheter varierar tillsammans med varandra. Däggdjur har till exempel en skalfördel
Topological protection in photonics offers new prospects for guiding and manipulating classical and quantum information. The mechanism of spin-orbit coupling promises the emergence of edge states that are helical, exhibiting unidirectional propagation that is topologically protected against back scattering. We directly observe the topological states of a photonic analog of electronic materials ex
Three-dimensional (3D) bioprinting is an appealing approach for building tissues; however, bioprinting of mini-tissue blocks (i.e., spheroids) with precise control on their positioning in 3D space has been a major obstacle. Here, we unveil "aspiration-assisted bioprinting (AAB)," which enables picking and bioprinting biologics in 3D through harnessing the power of aspiration forces, and when coup
Simulating computationally intractable many-body problems on a quantum simulator holds great potential to deliver insights into physical, chemical, and biological systems. While the implementation of Hamiltonian dynamics within a quantum simulator has already been demonstrated in many experiments, the problem of initialization of quantum simulators to a suitable quantum state has hitherto remaine
Bone structure and function are maintained by well-regulated bone metabolism and remodeling. Although the underlying molecular and cellular mechanisms are now being understood, physiological and pathological states of bone are still difficult to predict due to the complexity of intercellular signaling. We have now developed a novel in silico experimental platform, V-Bone, to integratively explore
Bones adapt to mechanical forces according to strict principles predicting straight shape. Most bones are, however, paradoxically curved. To solve this paradox, we used computed tomography–based, four-dimensional imaging methods and computational analysis to monitor acute and chronic whole-bone shape adaptation and remodeling in vivo. We first confirmed that some acute load-induced structural cha
Oxygen vacancies often determine the electronic structure of metal oxides, but existing techniques cannot distinguish the oxygen-vacancy sites in the crystal structure. We report here that time-resolved optical spectroscopy can solve this challenge and determine the spatial locations of oxygen vacancies. Using tungsten oxides as examples, we identified the true oxygen-vacancy sites in WO 2.9 and
We have studied the charge to spin conversion in Bi 1– x Sb x /CoFeB heterostructures. The spin Hall conductivity (SHC) of the sputter-deposited heterostructures exhibits a high plateau at Bi-rich compositions, corresponding to the topological insulator phase, followed by a decrease of SHC for Sb-richer alloys, in agreement with the calculated intrinsic spin Hall effect of Bi 1– x Sb x . The SHC
Hexagonal boron nitride (hBN) is an insulating two-dimensional (2D) material with a large bandgap. Although known for its interfacing with other 2D materials and structural similarities to graphene, the potential use of hBN in 2D electronics is limited by its insulating nature. Here, we report atomically sharp twin boundaries at AA'/AB stacking boundaries in chemical vapor deposition–synthesized
Water-in-salt (WIS) electrolytes provide a promising path toward aqueous battery systems with enlarged operating voltage windows for better safety and environmental sustainability. In this work, a new electrode couple, LiV 3 O 8 -LiMn 2 O 4 , for aqueous Li-ion batteries is investigated to understand the mechanism by which the WIS electrolyte improves the cycling stability at an extended voltage
Glioblastoma multiforme (GBM) is a lethal type of brain tumor that often develop therapeutic resistance over months of chemotherapy cycles. Recently, 3D GBM models were developed to facilitate evaluation of drug treatment before undergoing expensive animal studies. However, for long-term evaluation of therapeutic efficacy, novel approaches for GBM tissue construction are still needed. Moreover, t
Wave concentration beyond the diffraction limit by transmission through subwavelength structures has proved to be a milestone in high-resolution imaging. Here, we show that a sound wave incident inside a solid over a diameter of 110 nm can be squeezed through a resonant meta-atom consisting of a nanowire with a diameter of 5 nm equal to /23, where is the incident acoustic wavelength, correspondin
The layered antiferromagnetic MnBi 2 Te 4 films have been proposed to be an intrinsic quantum anomalous Hall (QAH) insulator with a large gap. It is crucial to open a magnetic gap of surface states. However, recent experiments have observed gapless surface states, indicating the absence of out-of-plane surface magnetism, and thus, the quantized Hall resistance can only be achieved at the magnetic
Microsupercapacitors (MSCs) have garnered considerable attention as a promising power source for microelectronics and miniaturized portable/wearable devices. However, their practical application has been hindered by the manufacturing complexity and dimensional limits. Here, we develop a new class of ultrahigh areal number density solid-state MSCs (UHD SS–MSCs) on a chip via electrohydrodynamic (E
Controlling the flow of matter down to micrometer-scale confinement is of central importance in material and environmental sciences, with direct applications in nano and microfluidics, drug delivery, and biotechnology. Currents of microparticles are usually generated with external field gradients of different nature (e.g., electric, magnetic, optical, thermal, or chemical ones), which are difficu
The lithium metal anode (LMA) is considered as a promising star for next-generation high-energy density batteries but is still hampered by the severe growth of uncontrollable lithium dendrites. Here, we design "spansules" made of NaMg(Mn)F 3 @C core@shell microstructures as the matrix for the LMA, which can offer a long-lasting release of functional ions into the electrolyte. By the assistance of
Strain-sensitive Ba x Sr 1– x TiO 3 perovskite systems are widely used because of their superior nonlinear dielectric behaviors. In this research, new heterostructures including paraelectric Ba 0.5 Sr 0.5 TiO 3 (BSTO) and ferroelectric BaTiO 3 (BTO) materials were epitaxially fabricated on flexible muscovite substrate. Through simple bending, the application of mechanical force can regulate the d
The unusual correlated state that emerges in URu 2 Si 2 below T HO = 17.5 K is known as "hidden order" because even basic characteristics of the order parameter, such as its dimensionality (whether it has one component or two), are "hidden." We use resonant ultrasound spectroscopy to measure the symmetry-resolved elastic anomalies across T HO . We observe no anomalies in the shear elastic moduli,
Much is known about the effects of antibiotics on isolated bacterial species, but their influence on polybacterial communities is less understood. Here, we study the joint response of a mixed community of nonresistant Bacillus subtilis and Escherichia coli bacteria to moderate concentrations of the β-lactam antibiotic ampicillin. We show that when the two organisms coexist, their population respo

Low self-esteem can lead you to feel worthless, unlovable, and unwanted. Feelings of low self-esteem have been directly linked to aggression, mood disorders such as anxiety and depression, eating disorders, and a general lower quality of life. By changing some of the things you do every day (how you dress, your posture, how you think of yourself), you can develop more confidence and higher levels
Researchers discovered two new species of prehistoric cockroaches dating back to when dinosaurs roamed the earth. These are the oldest human-known examples of "troglomorphic" organisms — critters that adapted to dwelling in caves. More work will be required to determine if the new roach species somehow survived the mass extinction that killed off the dinosaurs. An international research team disc
"Helicopter parenting, and all of its associated forms, prevents children from exploring their emotional and intellectual landscape, and often their physical landscape as well, such that they become adults in body only," says evolutionary biologist Heather Heying. Childhood is an important developmental stage that trains kids for messy, uncontrollable reality. If adults don't teach kids how to so
Elektroniske forløbsplaner er lanceret som redskaber til patientinddragelse og øget egenomsorg for KOL og diabetespatienter. Men forløbsplanerne åbner også mulighed for, at alment praktiserende læger kan dataunderstøtte indsatsen. Sidstnævnte fortjener mere opmærksomhed.
På tværs af almen praksis er der stor forskel på hvor ofte KOL- og diabetespatienter er i kontakt med sygehuset, viser en ny analyse fra forskningsenheden VIVE. Analysen peger på, at praksislæger med en mere systematisk brug af årskontroller kan mindske forskellen.
Praktiserende læger kan nu udskrive medicinsk cannabis kapsler til bl.a. kræftpatienter og smertepatienter, og kapslerne gør det muligt at sikre en mere præcis daglig dosering, siger professor. Men i almen praksis er lægerne stadig skeptiske. Midtvejsstatus på forsøgsordningen i løbet af foråret, oplyser ministeriet.
Sundhedsdatastyrelsen burde få lige så meget kritik for Landspatientregistrets manglende data et helt år, som Ringsted Sygehus har fået for mangelfulde brystkræftscreeninger, mener tidligere RKKP-direktør, Paul Bartels.
På søndag er det kvindernes internationale kampdag, og verden over sættes der fokus på kvinders manglende ligestilling. I Danmark regnes vi for at være langt fremme med ligestillingen, selvom det stadig halter med kvinder i topledelse og bestyrelser, både i det offentlige og det private erhvervsliv.
For 135 år siden blev Nielsine Nielsen Danmarks første kvindelige læge. Dermed banede hun vejen for alle os andre kvindelige læger. I dag er flertallet af læger kvinder, og kønsfordelingen bliver endnu mere skæv de kommende år. Gør det egentlig noget?
Den timehonorerende tilgang ved regionsklinikken på Bornholm giver lægen idéelle vilkår til at tage hånd om multisyge borgere. Lægen får ro til at optimere sin indsats ved at indgå i tæt samarbejde med kommune og hospital, viser en ny analyse fra forskningsenheden ViVE.
Sundhedsdatastyrelsen er aldrig blevet advaret af RKKP mod at organisere data i landspatientregistret efter forløb. Og det ifølge styrelsens direktør Lisbeth Nielsen med god grund, da data i det nye register fortsat også er knyttet til kontakterne.
Sundhedsdatastyrelsen har undervurderet opgaven med at organisere og validere data i det nye landspatientregister. Det mener flere medlemmer af den midlertidige referencegruppe, som styrelsen nedsatte for at få styr på problemerne med implementeringen.
I november overtog 35-årige Kristoffer Sønderstrand Jacobsen patienterne fra den midlertidige regionsklinik på Frederiksberg. Indtil videre har han drevet klinikken som selvstændig sololæge, men ligesom størstedelen af sin generation, vender han om kort tid praksistypen ryggen.
Region Sjælland fik sidste år tilladelse til at drive sine egne lægeklinikker for at afhjælpe manglen på praktiserende læger. I denne uge åbnede den første i Nakskov. Indtil videre har regionen dog måttet sande, at det er svært at lokke de faste læger til.
Kommunernes sundhedshuse skal have fokus på de brede sundhedsydelser som eksempelvis rådgivning, behandling og pleje af visse kroniske patienter. Men husene må ikke specialiseres, de må ikke blive supersundhedshuse, skriver Else Smith.
This week on the podcast, we're bringing you the third and final episode from our Common Threads series, this time about trust in science.

SpaceX CEO and chief engineer Elon Musk desperately wants to go to Mars. And to get there, he's willing to put together an army of engineers at his space company's facilities in Boca Chica, Texas, to keep churning out Starship rocket prototypes — a massive stainless steel rocket, just shy of 400 feet — that he wants to use to one day ferry up to 100 passengers to distant planets. But failure is a

Dutch researchers at AMOLF and TU Delft have seen light propagate in a special material without reflections. The material, a photonic crystal, consists of two parts that each have a slightly different pattern of perforations. Light can propagate along the boundary between these two parts in a special way: It is "topologically protected," and therefore does not bounce back at imperfections. Even wh
A polymer that can be broken down into its molecular building blocks, which can then be recombined by either heating or cooling—but by different mechanisms in each case—has been developed by RIKEN chemists. This could lead to intrinsically recyclable and sustainable plastics that depolymerize on demand.
One of the big questions in physics and chemistry is, how were the heavy elements from iron to uranium created? The Argonne Tandem Linac Accelerator System (ATLAS) at the U.S. Department of Energy's (DOE) Argonne National Laboratory is being upgraded with new capabilities to help find the answer to that question and many others.
Scientists and engineers working at the frontier of nanotechnology face huge challenges. When the position of a single atom in a material may change the fundamental properties of that material, scientists need something in their toolbox to measure how that atom will behave.
Chlamydia, a type of pathogenic bacteria, need to penetrate human cells in order to multiply. Researchers from Heinrich Heine University Duesseldorf (HHU) have now identified the bacterial protein SemC, which is secreted into the cell and restructures the cell membrane at the entry site. SemC forces the cell's own protein SNX9 to assist it in this process.
Chlamydia are infamous for causing sexually transmitted infections in humans and animals or even amoeba. An international team of researchers have now discovered diverse populations of abundant Chlamydia living in deep Arctic ocean sediments.

Tailoring the dimensions and other attributes of carbon nanotubes can substantially boost the amount of light they emit, three physicists at RIKEN have discovered. This finding promises to lead to the development of highly efficient photonic devices.
Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova.
A relatively new theory that identifies universal concerns underlying human judgment could be key to helping people with opposing views on an issue coax each other to a different way of thinking, new research suggests.
Asteroid Bennu's most prominent boulder, a rock chunk jutting out 71 ft (21.7 m) from the asteroid's southern hemisphere, finally has a name. The boulder—which is so large that it was initially detected from Earth—is officially designated Benben Saxum after the primordial hill that first arose from the dark waters in an ancient Egyptian creation myth.
A research team at the Tokyo Medical and Dental University (TMDU), RIKEN, and the University of Tokyo have demonstrated how to increase the lifetime of qubits inside quantum computers by using an additional "filter" qubit. This work may help make higher fidelity quantum computers that can be used in financial, cryptographic, and chemistry applications.
For the new space race, astronauts and space tourists will want to eat a little better than the corn beef sandwiches, applesauce and high-calorie cubes of protein, fat and sugar consumed by NASA scientists in the 1960s.
The holly genus, Ilex L., in the monogeneric Aquifoliaceae, is the largest woody dioecious genus (more than 664 species). It has a very uniform reproductive biology and is instantly recognizable in flower or fruit, although leaf morphology is diverse and growth forms range from prostrate shrubs to tall trees.
The greater sage-grouse is an iconic bird that lives in the western United States, and its populations are in decline. A new study published in the Journal of Wildlife Management reveals that energy development has negative impacts on sage-grouse reproduction.
Many things change for astronauts when they leave Earth and head into space, but at least one remains the same: They need food and water. NASA recently awarded funding to two University of Arizona teams to search for water and grow food in space.
In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to "recruit" neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they help carry out quantum operations.
NASA's Artemis Program is planning to land astronauts on the moon's south pole. To prepare for this, NASA's Solar System Exploration Research Virtual Institute (SSERVI) is creating the Lunar South Pole Atlas (LSPA). As part of that atlas, NASA is mapping the topography of the region, including the mountains.
In many situations, it's fair to say that light travels in a straight line without much happening along the way. But light can also hide complex patterns and behaviors that only a careful observer can uncover.

Lundabiologerna Linus Hedh och Anders Hedenström ville ta reda på var arten större strandpipare (Charadriu
New research raises serious concerns with the performance of some arsenic test kits commonly used in Bangladesh to monitor water contamination. Researchers tested eight commercially available arsenic test kits, and found that several—including the most widely used in Bangladesh—performed poorly. "The implication is that well waters could have arsenic well above the safe drinking water limit, even
Perhaps the star Betelgeuse isn't dimming because it's about to explode—it's just dusty. Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as a massive supernova. In a paper accepted by Astrophysical Journal Letters and available
Homogenization may threaten ecosystems at larger geographic scales, new research on North American birds suggests. The new study finds that the regional stability of ecosystems over time depends on both the total number of species present in a locality and on the variation in species identities among localities. "Changes that lead to something like biotic homogenization could be destabilizing for
Inhibiting a protein found in cancer cells in the gut may make radiation for colorectal cancer more effective, researchers report. The approach also helps protect healthy tissue from the negative effects of radiation. Studying cells, mice, and tumor samples from patients with cancer, the scientists targeted an enzyme known as indoleamine 2,3 dioxygenase 1 (IDO1). Treating tumor cells with a drug
As telescopes acquire more power, studies of exoplanets grow more sophisticated, and planetary missions produce new data, there's potential for much broader effects across Earth sciences, researchers argue in a new paper. "We don't only look at other planets to know what's out there. It's also a way for us to learn things about the planet that's under our own feet," says Mathieu Lapôtre, an assis
There's an association between gun purchaser licensing laws that require an in-person application or fingerprinting and an estimated 56% fewer fatal mass shootings in states that have the laws, according to a new study. Researchers analyzed fatal mass shootings in 45 states between 1984 and 2017 and the association between the rates of those shootings and the presence of various firearm laws. "Wh
The popular e-cigarette brand Juul may have so much influence over high school students' perceptions of vaping, that some teens don't consider themselves users. The ubiquity of the term "Juuling" has created challenges for measuring e-cigarette use, so in a 2018 tobacco focused survey of 4,183 public high school students in New Jersey, researchers added Juul specific questions to assess e-cigaret
Large LGBT friend groups can protect people's health, research finds. A big social network—particularly with people who share your sexual identity—reduces the harmful effects of LGBT discrimination on health, according to the study. "When we reviewed past studies, we found a pretty stark bias toward studying what made things worse," says William Chopik, assistant professor of psychology at Michig
The presence of a large audience boosts enjoyment, but it takes just a few haters to ruin a TV show or movie, a new study of social television shows. Social television is the practice of simultaneously watching television programs while seeing the social media messages of other viewers displayed on the same screen. Participants who perceived that other people disliked a movie were less likely to

Nature, Published online: 06 March 2020; doi:10.1038/d41586-020-00596-2 Complexes that are central to nerve-cell function might predate the split between bacteria and the lineage that led to more-complex organisms.
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-14749-4 Unique electronmagnetic response of Weyl semimetals have only been reported in static field regime. Here, the authors report evidence of a dynamical chiral anomaly response realized by internal collective lattice deformation with an external static magnetic field in a Weyl semimetal NbAs.
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-14800-4 Human affect is shaped in part by whether desirable states are achieved under personal control. Here, the authors show that control beliefs affect happiness and pride, and how those effects relate to neural responses in the prefrontal cortex and behavioral preferences for exerting control.
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-14857-1 The composition and tectonic affiliation of Earth's earliest crust remains disputed. Here, the authors find that Archean Jack Hills zircons crystallized from melts with compositions similar to andesite formed in modern subduction settings, which they suggest is consistent with an early onset of modern-style pla
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-15006-4 Ubiquitylation of histone H3 (H3Ub2) by UHRF1 recruits DNMT1 to chromatin, which is essential for DNA methylation inheritance. Here, the authors provide evidence that there are two distinct mechanisms underlying replication timing-dependent recruitment of DNMT1 through PAF15Ub2 and H3Ub2, both of which are requ
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-15022-4 While genome-wide association studies have yielded thousands of trait-associated loci, identifying causal variants remains challenging. Here, the authors perform seven genomics assays in various cell types to prioritize genetic variants in the TNFAIP3 locus, and report high-priority variants within disease-asso
Nature Communications, Published online: 06 March 2020; doi:10.1038/s41467-020-15027-z Breast cancer is frequently diagnosed using ultrasound. Here, the authors show that, in addition to ultrasound, shear wave elastography can be used to diagnose breast cancer and, in conjunction with deep learning and radiomics, can predict whether the disease has spread to axillary lymph nodes.
Vγ9Vδ2 T cells are a major γδ T cell population in the human blood expressing a characteristic Vγ9JP rearrangement paired with Vδ2. This cell subset is activated in a TCR-dependent and MHC-unrestricted fashion by so-called phosphoantigens (PAgs). PAgs can be microbial [(E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate, HMBPP] or endogenous (isopentenyl pyrophosphate, IPP) and…
Pupillometry, a noninvasive measure of arousal, complements human functional MRI (fMRI) to detect periods of variable cognitive processing and identify networks that relate to particular attentional states. Even under anesthesia, pupil dynamics correlate with brain-state fluctuations, and extended dilations mark the transition to more arousable states. However, cross-scale neuronal activation…
Visuomotor impairments characterize numerous neurological disorders and neurogenetic syndromes, such as autism spectrum disorder (ASD) and Dravet, Fragile X, Prader–Willi, Turner, and Williams syndromes. Despite recent advances in systems neuroscience, the biological basis underlying visuomotor functional impairments associated with these clinical conditions is poorly understood. In this study, we
Most hepatocellular carcinomas (HCCs) develop in patients with chronic hepatitis, which creates a microenvironment for the growth of hepatic progenitor cells (HPCs) at the periportal area and subsequent development of HCCs. We investigated the signal from the inflammatory liver for this pathogenic process in the hepatic conditional β-catenin knockout mouse…
The ubiquitous gasotransmitter hydrogen sulfide (H2S) has been recognized to play a crucial role in human health. Using cystathionine γ-lyase (CSE)-deficient mice, we demonstrate an unexpected role of H2S in Mycobacterium tuberculosis (Mtb) pathogenesis. We showed that Mtb-infected CSE−/− mice survive longer than WT mice, and support reduced pathology and…
Adipose tissue provides a defense against starvation and environmental cold. These dichotomous functions are performed by three distinct cell types: energy-storing white adipocytes, and thermogenic beige and brown adipocytes. Previous studies have demonstrated that exposure to environmental cold stimulates the recruitment of beige adipocytes in the white adipose tissue (WAT)…
Pluripotent embryonic stem cells (ESCs) contain the potential to form a diverse array of cells with distinct gene expression states, namely the cells of the adult vertebrate. Classically, diversity has been attributed to cells sensing their position with respect to external morphogen gradients. However, an alternative is that diversity arises…
Carotenoids play a number of important roles in photosynthesis, primarily providing light-harvesting and photoprotective energy dissipation functions within pigment–protein complexes. The carbon–carbon double bond (C=C) conjugation length of carotenoids (N), generally between 9 and 15, determines the carotenoid-to-(bacterio)chlorophyll [(B)Chl] energy transfer efficiency. Here we purified and spec
City-size distributions are known to be well approximated by power laws across a wide range of countries. But such distributions are also meaningful at other spatial scales, such as within certain regions of a country. Using data from China, France, Germany, India, Japan, and the United States, we first document…
Chronic inflammation during Alzheimer's disease (AD) is most often attributed to sustained microglial activation in response to amyloid-β (Aβ) plaque deposits and cell death. However, cytokine release and microgliosis are consistently observed in AD transgenic animal models devoid of such pathologies, bringing into question the underlying processes that may be…
Annie Jump Cannon joined the Harvard Observatory in 1896 to help build the official classification system for stars, based on heat profiles. Her calculations were largely drawn off the atmospheric refraction in telescopic photos rather than in situ observations; she and her fellow female colleagues earned about half of the men in their positions. The university didn't designate Cannon as an astro

When NASA mathematician Katherine Johnson retired in 1986, she'd spent three-plus decades at the agency and only seen a handful of American women go into space. One, of course, was Sally Ride in 1983; the second was Judith Resnik, who died in the Space Shuttle Challenger disaster. But it wasn't for a lack of potential. "Girls are capable of doing everything men are capable of doing," Johnson said

In the 20th century, humans made great progress in developing mechanisms to insulate themselves from the worst that mother nature had to throw at them. We created antibiotics to protect ourselves from deadly bacteria, we created pesticides to ward off destructive insects, we dammed up rivers to kingdom come to protect against the sudden shocks in water flow that result in drought and floods, we c
Robots hold promise for a large number of people with neurological movement disorders severely affecting the quality of their lives. Now researchers have tapped artificial intelligence techniques to build an algorithmic model that will make the robots more accurate, faster, and safer when battling hand tremors. They report the most robust techniques to date to characterize pathological hand tremor
Scientists have designed a tunable graphene device for experiments in exotic physics, where superconducting, insulating, and magnetic properties can be observed in a single system. The technology could advance the development of next-generation memory devices and quantum computers.
Researchers have come up with a new type of nanoelectromechanical relay to enable reliable high-temperature, non-volatile memory. The work is an important development for all-electric vehicles and more-electric aircraft which require electronics with integrated data storage that can operate in extreme temperatures with high energy efficiency.
Researchers analyzed genetic material of red foxes (Vulpes vulpes) inhabiting Berlin and its surroundings. They identified two genetically distinct, adjacent 'urban' and 'rural' fox populations and revealed that physical barriers such as rivers or man-made structures reduce the exchange between these populations but also differences in human activity in these landscapes play a major role.
An international team of astronomers has captured the very moment when an old star first starts to alter its environment. The star has ejected high-speed bipolar gas jets which are now colliding with the surrounding material; the age of the observed jet is estimated to be less than 60 years. These features help scientists understand how the complex shapes of planetary nebulae are formed.
In 1996, Agnes Binagwaho returned home to Rwanda in the aftermath of its genocide. She considered leaving amid the overwhelming devastation, but women in her community motivated her to stay and help rebuild — and she's glad she did. In an inspiring talk, Binagwaho reflects on her work as Rwanda's former Minister of Health and discusses her new women's education initiative for the country, which s

A few years ago, I wrote a song called " Five Minutes ." This week, after tornadoes ripped through Nashville, a friend texted me a line from my song: "In five minutes, your whole life can change." In the early hours on Tuesday, my husband received a phone call from his son, warning us that a tornado was headed our way. A middle-of-the-night phone call is enough to send my adrenaline soaring, and
Illustration: Mikel Jaso; rendering: Borja Alegre A n entire generation is losing faith in American capitalism. Widening inequality and declining mobility have led to an erosion of trust in the system. In a 2018 Gallup survey, only 45 percent of young adults said they supported capitalism. Fifty-one percent supported socialism. These numbers are stark, and so are the failures that underlie them,
Every year on March 8, International Women's Day promotes gender equality —a term that leaves room for many interpretations, some of them contradictory. For example, the historian Paula J. Giddings describes how America's early feminist organizations excluded women of color, including the journalist and activist Ida B. Wells, who worked for suffrage and black civil rights. Today, attitudes about
David Plouffe got it very wrong in 2016. After confidently predicting Donald Trump's defeat, the campaign manager credited with Barack Obama's historic 2008 victory watched a reality-television star become commander in chief. Four years later, Plouffe says he rewatched that Election Night. Over and over. And after absorbing the lessons of that day, he's written a book on what Democrats need to do

It was freezing cold with gusting winds in Indianapolis on New Year's Day 1978. While much of the city was presumably waking to a hangover, the Islamic Teaching Center was busy hosting prominent preachers from the Middle East. Among them was Abdallah Azzam, a 36-year-old rising star of the Jordanian Muslim Brotherhood. In Indianapolis, Azzam would meet a young Saudi student with a now-famous name
How do you keep track of what page you're on in a book? The answer tells you everything you need to know about the moral lens through which you view the world. At least, that's according to a chart that was widely circulated on Twitter last month (and originally shared on Tumblr ). The axes of the nine-square grid—lawful, neutral, chaotic across the top; good, neutral, evil down the side—assign e
Vera Golubeva spent more than six years in one of Joseph Stalin's gulag camps . Her crime? "To this day, I still don't know," she says. In a new documentary from Coda Story , Golubeva remembers the excruciating details of her imprisonment. When she was arrested, along with her father, mother, and sister, Golubeva was taken to KGB headquarters and tortured. She was eight months pregnant. "I felt a
My father, Arnold Bodmer, who has died aged 90, fled Nazi Germany as a child refugee. In Britain and later in the US he was a scientist renowned for formulating many innovations in nuclear physics, notably through his work on the behaviours of nuclei. His pioneering work, which he completed while on sabbatical at Oxford University in 1970-71, suggested the possibility of collapsed nuclei – a cruc
